Untuned cam and long trip to tune
Untuned cam and long trip to tune Hey I have a PATG spec cam im putting in possibly this weekend, and I was wondering if the car could make it to Orlando for the tune. It's a 226/230 .598 .600 113+4

If you have already had it tuned for the headers then it might be ok if you baby it. You will probably have some driveability issues though, so beware. The concern I would have is that it will run lean, especially if it hasn't already been tuned for the headers.
This subject drives me nuts.....
Guys/girls. Read this - From 1998-2000, we had absolutely NO TUNING for internal modifications, and raced all the time. Back then we drilled the TB hole, and for those who could afford it, put a MAFT on the car, and went to the dragstrip
Yes, tuning is necessary. Of course. Is it going to be the death of your engine if you drive it untuned with a cam or heads/cam? NO. We were rolling racing to 150mph with untuned heads/cam cars 10 years ago.
Of course this excludes turbo/supercharger/nitrous cars.

The reason for this is your car will adjust the fueling itself with STFT and LTFT under this RPM (why do you think we have those fancy O2 sensors?). After 4k you start relying on MAF and calculations that are wrong for your setup with no fuel trimming taking place, this CAN hurt your motor.
Is it going to idle bad, surge, and make lower power? YES.
Is it going to destroy your motor to cruise to your tuner on the highway? NO.
Your not going to wash down **** unless you put in bigger injectors.
umm I could understand doing that if you didnt have any tuning options back then. But it would be retarded to do that now with all kinds of tuning options
I agree with eamador11 your talking ten years ago when the options of tuning where at best none, and while you are very learned in many aspects of the LSx engine and you have given me much important info, tuning is a must in all cars today to get optimal performance.
I bet they ran like **** too.
Listen people, since reading comprehension must be on shortage today I'll spell it out. I never said "Hey you should always drive your car untuned". I was putting it into perspective, because people act like it's going to be catastrophic to your engine to drive it untuned for a while. In an N/A setup, especially a cam only or heads/cam car, this is silly nonsense. You can drive a car untuned, and it is not going to hurt anything as long as you aren't a moron and redlining at every red light. Should everybody do this? No. Should it be done at all? No. But if somebody is in a pinch or needs to drive elsewhere to get the car tuned, it isn't going to throw a rod through the hood like the internet mechanics will have you think. You're not committing murder to your engine driving it untuned for a few miles.

After installing my MS3 i drove it to work for a straight week, and then drove it from Miami to Tampa that friday on a stock tune to go get it tuned. That entire week though it did want to shut off a few times, but it wasn't to bad. But i never did pass 4k rpms or get on it at all since i was on the stock tune.

Guys things you should be aware of:
A big duration cam (mid 23x+) is a higher risk untuned for 2 reasons (1> It will be pig rich at idle and that could wash you cylinders), (2> It will be lean above 4K rpm and that could cause detonnation and kill your pistons)
Now for that smallish 226, it should be fine to reach that tuner. Things to avoid (staying at idle for too long a time (severe back to back traffic), going above 4K rpm or Wide open throttle to avoid lean condition)
Highway cruise speed will be best.
